A tabbed pane fires a change event whenever the selected tab is changed either by the user or programmatically.
// Create the tabbed pane
JTabbedPane pane = new JTabbedPane();
// Add tabs...; see e830 向JTabbedPane中加入一个卡片
// Register a change listener
pane.addChangeListener(new ChangeListener() {
// This method is called whenever the selected tab changes
public void stateChanged(ChangeEvent evt) {
JTabbedPane pane = (JTabbedPane)evt.getSource();
// Get current tab
int sel = pane.getSelectedIndex();
}
});
